Walking

So my LO is finally taking a few steps unaided, but keeps tripping on her own legs or it’s like her legs don’t hold her weight anymore and just falls down. I think the most steps she’s taken have been like 4-5 in a row. She’s been attempting more often today. Is it normal in the beginning for them to fall so often and for no reason (like tripping or hitting something)? And how soon after this stage did LO start walking fully without any assistance or falling?? I’ve been counting down I feel like we’re so behind :/
